ENVELOPE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 237,125, dated February 1, 1881.

Application liled October 4, 1880. (No model.)

To all whom it may concern Be it known that GEORGE H. PLAIGE, deceased, late of Springfield, in the county of Hampden and State of Massachusetts, in-

vented a certain new and useful Improvement in an Attachment to vEnvelope-Making Machines, commonly called a knock-off, of which the following is a description, reference being had to the accompanying drawings,

xo Where- Figure 1 is an end view of the attachment, with neighboring parts of an envelope-making machine. The full lines show the mechanism of the attachment in the position to receive an envelope. The dotted lines show the mechanism in the position of delivering an envelope. Fig. 2 is a top view of the attachment only. Fig. 3 is a front view of the attachment only.

The oflice of this attachment is to receive anenvelope -in a horizontal position and to carry it a little distance forward, and deliver it in a vertical or nearly vertical position.

The letter a denotes the table-frame of the attachment. The parts above this are neighboring parts ot' the envelope-making machine.

The letter b denotes the vertically-reciprocating table, on which the envelopes 'are de- 3o livered, one by one, in a horizontal position, while the table is at the top of its vertical play.`

The letter c denotes a guide-rod appurtenant to the table, through which the vertical 3 5 movement is given to the table. 1t is heldin a vertical position by sockets d, and it holds and supports the table, as well as gives it the vertical reciprocating motion.

The letters el denote two lingers, of which 4o there may be 011e or more, but preferably two,

which have at their free ends a motion transversely ofthe table, for the purpose of forcing -the envelope transversely or sidewise oft' the table into the receptaclef. These lingers are pivoted at their lower ends on the supporting-arms g, and have their peculiar motions given as follows: These lingers are mortised longitudinally, each of them, by mortise h h h" h", in which plays the pin t', carried on a lug projecting from the table, and the travel 5o of the pin in this mortise gives the finger its movement. The upper part of the mortise h is practically vertical, so that while the pin t is traversing it the linger remains practically stationary; then the next part of the mortise h runs obliqnely forward, so that the pin, in traversing it, moves the finger backward. The next part of the mortise, hf', is vertical, and the linger remains stationary While the pin traverses it. The lowest and 6o the last part of the mortise, h, runs obliqnely backward, so that the pin, in traversing it, moves the linger forward. When the pin moves upward all these movements are, of course, reversed 6 5 The lingers e carry hooks j to securely catch upon the edge of the envelope, and the upper ends of these carry the oblique surfaces lc, to change the position of the envelope from a horizontal to an oblique.

The table is mortised for the passage of the lingers e, or they might come up at the ends of the table.

Theoperation of the device is that an envelope being delivered upon the table the table moves downward, leaving the envelope upon the ends of the lingers, which carry it forward and drop it into the rcceptaclef in a practically vertical position.

I claim as the invention of the said GEORGE 8o H. PLAICE- The combination of the mortised and verticall y-reciprocatin g table b, carrying the pins t', with the pivoted and reciprocating lingers e, having the mortses t h It h", the hooks j, and the obliqued tops lr, all as described.
